srncrrrca'rron forming WILLIAM noon, on BROOKLYN, new YORK.

part of Letters Patent No. 250,754, dated December 13, 1881.

Application filed Octoberli, 1881. (No specimens.)

i To all whom it may concern:

Be it known thatj-I, WILLIAM PUGH, of Brooklyn, Kings county, State of New York, have invented an Im provementin Processes of and Compounds for Waterproofing and Presrvvi ng floods, of which the following descripticnis .aspecificatioin I v Theobject of ny iniprovement is to render -..-mi ldew"a'nd moth proof and water-proof all kinds of textile and vegetable fibers and fabrics, such as felt and felted manufactures,cot-' ton, linen, or.hempen cordage, and twine, pa-

per, 850. Y

This improvement is especially useful for waterproofing lire hose and protecting it against mildew, whether made of cotton, linen, or leather, and also for preserving woolen and "other goods oi all kinds, it rendering them moth and water-proof.

In subjecting'materials proved process they are tinct and separate baths, the first of which I prepare as follows: I take one (1) part of resin and one-third part of caustic soda, and one- 2 eighth (g) part of caster-oil, and I dissolve them iogetherin one hundred and twenty-eight (128) parts of water by means of heat. When thoroughly dissolved and of uniform consistency I add to this solution a suflicient amount of sali- 0 cylic acid or its equivalent, (instead of the salicylic acid acetate of aluminamay sometimes be used odvantageously,) stirring it well in on der to make the combination perfect, when'the first bath is ready for use. The goods to be rendered mildew, moth, and water proof are placed in this first bath and allowed to remain four hours, more or less, according to their weight and quality. The goods are then to be taken from this both and'wrung out or well 40 drained, when they are ready to be treated in the second bath, which is prepared as follows: I take four parts of sulphate of copper, six parts of sulphate of zinc, six parts of potashalum (aluminum potassium sulphate, and one twenty-fourth 9;) part of carbonate of soda or equivalent alkali, and 1 dissolve them in thirty two parts of boiling water. I then take nine parts of acetateof lead and dissolvein thirty-two 20 to my new main goods ivhi hat-h,

treated in three dis 1 a drained and dried;

parts of boiling water. When both compounds are dissolred I enter the latter into tho former 5c and mix them well together, after which the mixture is allowed to standa suttlcient time for tile precipitate to settle. Sulphate ot' alumina may be used instead of the potaslr alum} When this compound has become per- 5 fectlyf clear it is drawn or siphoned oif from the precipitateinto a suitable vessel.

I then, preferably, take one-half (11;) part of chloride of sodiuniand dissolve it in four parts of boiling water, making the second bath'ready for use. The ch have been treated in the first as above stated, are now placed in this iecond bath and allowed to remain for half an our, their weight and quality, after which they are removed and wrung out or well drained.

The third bath is simply water, in which the articles treated as described are well and add it to the said clear compound,

more or less', depending, as before, on

washed, and then removed and wrung out or In the second bath the ingredients may be somewhat varied, but the-compound given produces the best results. For instance, the

carbonate of soda may be omitted, in which 7 5 case a largeramount of acetate of lead should be used, and the sulphate of copper might be replaced by an additional amount of potashalum. The solutio omitted, but its use improves the quality of the goods treated, and renders them less lia-' ble to be injured by heat.

I claim-- 1. The herein-described bath, consisting of 8 resin, caster-oil, caustic soda, and salicylic acid, or equivalent, for the purpose of rendering material mildew=proot', substantially as described.

2. The herein-described bath,containing the go following ingredients: sulphates of copper and zinc, carbonate of soda, or equivalent, and acetate of lead, insubstantially the proportions described, for treating material in the process of waterproofing, substantially as set forth.

3. in a bathfor treating material in the process of waterproofing, sulphate of zinc, potash-alum, or equivalent, carbonate of soda, or

. h of chloride of sodium might be it: 4

equivalent, and acetate of lead, compounded in testimony whereof i have siguedl myiiume substantially as and in the proportions deto this specification in the presence of tuoeuhscribed. scribing witnesses;

4. The herein-described bath, oousisling of WILLIAM USE 5 sulphates of copper and zinc, potash-alum, Vituesses:

carbonate of soda, acetate of lead, and sodium.
